6. 15. An evaluation of deterministic prediction of ocean waves using pressure data to assist a Wave Energy Converter

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Niclas Bassili; Douglas Eriksson; [2020]
   Keywords : Deterministic wave prediction; Pressure sensor; Weakly dispersive reconstruction method; Time to spatial data assimilation; High-order spectral method; Determinisk vågförutsägelse; Trycksensor; Weakly dispersive reconstruction method; Time to spatial data assimilation; High-order spectral method;

   Abstract : Currently, existing devices for extracting electrical power from ocean waves all suffer from problems with low efficiency due to a lack of information about the incoming waves in advance. The complex dynamic nonlinear characteristics of the ocean make the prediction of these incoming waves a great challenge. READ MORE
